72" x 96" BA-DDRHGA Double Leaf Domed Aluminum & Steel Equipment Hatch
Getting large equipment onto a rooftop can be a real challenge, especially when dealing with tight spaces and unpredictable weather. A bulky, heavy hatch cover makes the job even harder, slowing things down and increasing the risk of injuries.
The 72" x 96" BA-DDRHGA Double Leaf Domed Aluminum & Steel Equipment Hatch provides a practical solution. Its dual-cover design splits the weight, so instead of struggling with a single heavy lid, you get a smoother, more manageable lift. Plus, built-in lift assist springs help open the hatch effortlessly.
Whether you're installing equipment or performing routine maintenance, this hatch gives you a hassle-free experience from start to finish.
Why Choose the 72" x 96" BA-DDRHGA?
- Built to Last: Made from durable aluminum and steel, this hatch stands up to harsh weather.
- Brighter Workspaces: The domed polycarbonate lid lets in natural light, cutting down on energy costs.
- Easy Access: The split cover design reduces weight, making opening and closing much easier.
- Effortless Operation: Lift assist springs help minimize strain, so you don’t have to struggle.

Installation Instructions
- Cut the Roof Opening: Mark and cut an opening that matches the hatch size (measured from inside curb to inside curb). Make sure it's properly positioned to keep the roof structure strong and secure.
- Set the Hatch in Place: Carefully place the hatch over the opening, ensuring it sits flat and level. If needed, use shims to keep it aligned and prevent any twisting.
- Secure the Hatch: Fasten the curb flange to the roof frame using the right screws or bolts. For wood frames, #10 screws work well, but you may need larger bolts for extra strength.
- Final Checks: Finish the roofing around the hatch following local building codes. Remove safety bands from the door sides and open the hatch carefully—spring-loaded doors might pop open if the latches shifted during shipping.
